Question

OK i have a problem i have to find the percentage that the price went up so i have .57 cents and then it went up to 62 cents show me how to do this please help

Answer 1

The price went up by 8.77%

Explanation:

Let

57 cents be "old value" and 62 cents be the "new value"

Percentage increase is always given by:

Percentage Increase =
`(new-old)/(old)*100`

Substituting these values into the formula gives us:

`(new-old)/(old)*100\\=(62-57)/(57)*100\\=0.0877*100\\=8.77`

Hence the price went up by 8.77%
